CARTON-FILLING MACHINE.

Application filed February 19, 1921. Serial No. 446,420.

To all w/mm if may concern:

Be it known that. we, Jnssn \VATsoN AN- nunws and HARRY L. EVANS, citizens of the United States, residingat Newport, in the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Carton-Filling Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same,- reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a 15" part of this specification.

The present invention relates, generally, to improvements in machines for automatically filling and closing cartons and similar goods containers; and the invention has for its principal object to provide an improved automatic machine for successively feeding, setting up or opening, and holding collapsed cartons, filling the same with goods, and then closing the side flaps and tucking in the end flaps to simultaneously close both ends of the cartons to retain the inserted goods therein, all in a rapid and assured manner, and while retaining the cartons in horizontally disposed position throughout the performance of said operations so that comparatively little bodily movement and shifting of the same is required, whereby the risk of tearing or mutilating the cartons is reduced to a minimum, and waste of carton material is consequently eliminatedJ Another object of this invention is to provide in combination with the carton handling mechanism, a novel construction of means for inserting thereinto the goods to be enclosed therein, in a rapid manner and with a minimum risk of injury either to the said goods or to the cartons,

Another object of this invention is to. provide a novel means for shaping or folding the end closing flaps preparatory to tucking the same into the carton ends, together with a positive and simple means for producing A the tucking movements of said end flaps.

Other objects of the present invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.

With the various objects of the invention in view, the same consists, primarily, in the noval carton filling and closing machine herelnafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described, and then finally embodied in the claims appended hereto.

The invention is clearly illustrated in the accompanying drawings, in which z- Figure l is a side elevation of the novel machine, embodying the principles of the present invention; Figure 2 is a horizontal section of the same, taken on line 22 in said Figure 1; Figure 3 is a detail transverse vertical section, taken on line 3-3 in Figure 2; Figure 4 is a detail vertical longitudinal section, taken on line 4-4 in Figure 2, and drawn on an enlarged scale; Figure 5 is a View similar to Figure 4, but illustrating further operated positions of the parts shown in said latter figure; Figure 6 is a detail transverse vertical section, taken on line 66 in Figure 2; Figure 7 is a detail view similar to that shown in Figure 6, and drawn on an enlarged scale, to illustrate an operation of the filling or charging plungers preliminary to the insertion of goods into a carton; Figure 8 is a view similar to that shown in Figure 7, but illustrating further advanced operative positions of the carton filling or charging plungers; Figure 9 is a detail longitudinal vertical section, taken on line 99 in Figure 2 and drawn on an enlarged scale; Figure 10 is a detail plan View of the receiving end of the carton closing means, drawn on an enlarged scale; Figure- A 11 is a planview of the carton closing means, drawn on an enlarged scale, and illustrating diagrammatically the procedure of a carton therethrough to produce the closing and tucking of the carton end flaps; Figures 12, 13, 14, 15 and 16 are respectively transverse sections on lines 12-12, 13-13, 14-14, 15-15 and 16-46 in Figure 11, to show the progressive operations carried out in closin and tucking the carton end flaps; Figures 1 and 18, are views similar to that shown in Figure 16,'the same illustrating progressive operative movements of rotary tucking members; Figure 19 is a detail horizontal sec-.

tion taken on line 19-19 in said Figure 16; and Figure 20 is an enlarged plan View of at Geneva movement for producing the timed intermittent driving of a rotary conveyor or turn-table for successively receiving, holding, and feeding the cartons to the filling and closing means.

Similar characters of reference are employed in all of the hereinabove described views to indicate corresponding parts.

Referring now to the drawings, the reference character 1 indicates a suitably supported base plate or bed, upon which is in turn supported, by standards 2, a table 3, which is spaced above said bed in horizontal parallel relation thereto. Journaled in bearings 4, fixed to said bed 1 beneath said table 3, is a driving shaft 5, which is driven by the chain 6 and sprocket 7, or any other desired power transmission means, from a suitable source of power. J ournaled in bearings 8 provided in said standards 2, at one side of the machine, is a longitudinal lay shaft 9, which is driven by the driving shaft 5 through the gear wheels 10 and 11. Journaled in bracket bearings 12, at one end of the machine, is a transverse lay shaft 13, which is driven from the lay-shaft 9 by the bevel gears 14 and 15. Journaled in bearings 16 provided in said standards 2, at the opposite side of the machine, is a second longitudinal lay shaft 17, which is driven from said transverse lay shaft 13 by the bevel gears 18- and 19. Fixed in a suitable location on said bed 1 is a foot-piece 20 in which is supported the lower end of a vertical column or shaft 21, the upper end of which extends through and above said table 3. Rotatably mounted upon the upper end of said column 21,.above said table 3,

is a horizontally disposed rotary conveyer.

or turn-table 22. Rotatably mounted upon the said column 21, beneath the table 3, is the female member 23 of a Geneva movement,

' the hub of which extends upwardly through said table 3 so that said turn-table 22 may be fixed thereto. The reference character 21 indicates a vertical shaft journaled to extend between said bed 1 and table 3, the same being driven from said driving shaft 5 by the bevel gears 25 and 26. Fixed on said vertical shaft 24, and driven thereby, is the male member 27 of said Geneva movement. The said Geneva movement operates to produce a desired intermittent and timed rotation of said turn-table 22.

Said turn-table 22 is provided with a plurality of openin s 28 in its marginal portions adjacent to its periphery, the same being equally spaced apart, and so positioned as to properly and successively aline themselves with carton feeding or delivery means at one point and carton filling means at another'pointlduring the intermittent stop periods of the turn-table movement. Pivoted at their inner ends within each opening 28 are vertically swinging gripping devices 29 provided at their free ends with upwardly projecting transverse gripping lugs 30. Fixed on said turn-table in associated relation to each opening 28 and its gripping device 29 is an abutment block 31, which when said gripping devices are raised to operative positions determine or limit a space intermediate the same and said gripping lugs 30 equal to the width of an expanded or opened carton. Supported upon said table 3, in proper associated relation to said turntable 22, is a suitably supported magazine 32, adapted to contain a vertical stack of collapsed cartons C. Means are provided to successively .feed the cartons (7 from the bottom of the stack thereoffand then deliver the same upon the turn-table 22 in proper relation to the gripping devices 29 thereof; said means being timed to deliver a carton, as the gripping devices are successively positioned or alined relative to the magazine by the intermittent rotation of the turn-table. Said carton delivery means comprlses a reciprocatory member 33 moving in guides 34:, and actuated by a lever 35 pivot-ed upon the table 3, said lever 35 being oscillated through interconnecting means by an eccentric 36 mounted on said transverse lav shaft 13. Connected with the free end of said reciprocatory member 33 is a plunger 37 adapted to engage and push outwardly from the magazine 32 the bottom carton of the stack, so that the same drops upon the surface of the turn-table 22 across said gripping device 29 positioned to receive the same, and in front of the abutment block 31. The delivery and fall of the collapsed carton being thus accomplished, a continued forward movement of the reciprocatory member 33 carries a positioning or pilot plate 38 (which is attached to said recipro catory member 33 so as to extend below and parallel to the plunger 37) into engagement with the collapsed carton, as it rests upon the surface of the turn-table and slides the same up to and against the abutment block 31 to properly position and aline the carton relative to the gripping means; all of which may bebetter understood by an inspection of Figures and 4 of the drawings. (onnected wvith said turn-table 22 in proper locational relation to each carton gripping means is a vertically movable stop pin 39 which is depressed bya spring 40 so that its upper end is normally withdrawn below or flush with the surface of said turn-table 22. When, however, a gripping means is carried by the movement of said turn-table into alinement with the carton delivery means, the adjacent stop-pin 39 engages with its lower end a lift-cam 41 which is fixed upon the table 3 in the path of its movement, and as the same rides upon said lift-cam 41 the turn-table 22 comes to a stop, thus leaving the upper end of said stop-pin 39 projected above the surface of the turn-table (see Figing at its forward end a sharpened nose 43 having a thin knife-edge periphery. Said clamp-blade 43 is so located relative to the turn-table 22, that the same is longitudinally alinedwith the collapsed carton as delivered upon the turn-table and registered against the abutment-block 31. Said clamp-blade 43 is of a width corresponding generally to the width of the interior of the carton C, when the latter is expanded or opened. Said clamp-blade is reciprocated in timed relation to the delivery of the collapsed carton upon the turn-table 22, so that, after the carton is registered against the abutment-block 31, the clamp-blade moves forward so as to enter the interior of the collapsed carton at one end to thereby engage and hold the underside of the latter down upon the surface of the turn-table; the carton being stopped against longitudinal displacement during the entrance ofthe clamp-blade thereinto by the engagement of its opposite end with the upwardly projected stop-pin 39 above described. In order to prevent crumpling of the flaps at the end of the carton abut-ting said stop-pin 39, or ridin up of said flaps over the stop-pin, under the pressure of the entering clamp-blade, with consequent danger of displacement of the carton from proper position, or danger of possible permanent injury to said flaps, there is provided a resilient presser foot 44, in the form of a leaf-spring'device, which is carried by a lever pivoted to the side of said guide bracket 42. A timed oscillation of said lever, in advance of the entry of said clampblade 43 into said carton, is produced by the action of a cam 46, fixed on said lay shaft 9, upon an anti-friction roller 47 carried by the outer end of said lever 45, whereby the presser foot 44 is swung downward into holding engagement with the end of said carton abutting said stop-pin 39. A spring actuated plunger 48, or other suitable means, maintains the roller 47 of the lever 45 in operative riding engagement upon said cam 46; all of said described parts, and their relation one to another, bein clearly illustrated in Figures 2 and 3 of t e drawings. The means for producing the desired timed reciprocatory movements of the clamp-blade 43, comprises a lever 49 pivoted on said bed 1, the upper free end of which is connectedthrough the link 50 with the rear end of said clamp-blade. The clamp-blade actuating oscillations of said lever 49 are produced by means of a connecting rod 51 having a bifurcated end riding on and guided by said driving shaft 5, said connecting rod having a'pin or roller 52 engaged in the cam groove 53 of'a cam-wheel 54 fixed upon and rotated by said driving shaft 5.

Initially the gripping devices 29 occupy a downwardly swung or depressed inoperative position so that their gripping lugs 30 are downwardly withdrawn below the surface of the turn-table 22. The collapsed cartons are scored longitudinally to demarcate the longitudinal faces C and-G and-sides C and (J of the same, see Figures 4 and 5. As delivered by the delivery means, the I collapsed carton rests upon the turn-table so that the sides G thereof in the plane of the lower or under face C is positioned over the downwardly withdrawn gripping lug 30. When the gripping device 29 is swung upwardly into operative position, the upward movement of the gripping lug 30 first engages and bends upwardly the side C, while the face C is held clamped against the surface of the turn-table 22' by the clamp-blade 43, thereby raising upward or lifting the face C and turning upward the side C against the abutment-block 31, thus expanding the carton to its longitudinally open condition ready for the insertion and reception of the goods to be enclosed therein. When thus expanded to its open condition, the raised gripping device 29 causes the carton to be gripped and held upon the turn-table surface, in such open condition, between the gripping lug 30 and the abut- 'ment-block 31 as shown in Figure 5. The

timed operation of the gripping device 29, to cause the said opening and gripping of the delivered carton, is produced by a vertic'ally reciprocated lifting-block 55 guided in an opening orway 55 provided in said table 3. extending beneath said table 3- has its inner end pivotallv connected with the lower end of said lifting-block 55. The said lever 56 is oscillated at proper times by a cam 57 mounted on said lay shaft 9 to operatively engage an anti-friction roller 58 on the outer end of said lever. The gripping device 29 is provided at its 'free end .with an antifriction or tracker roller 59 which is engaged by the lifting-block 55 as the latter moves upward to swing the gripping device into operative position. scribed operations resulting inthe delivery of a collapsed carton, the opening of the same, and the gripping of the same in supported relation to the turn-table 22, are all timed to take place while the turn-table 22 is stationary, or dwelling immovable during A lever 56 fulcrumed'upon and The above de- After the carton is delivered, opened, and

gripped in supported relation to and upon the turn-table 22, the clamp-blade 43 is withdrawn to initial position, the presser foot 44 is raised, and thereafter the turntable 22 resumes its rotative movement, which carries away the open carton, and alines the next or succeeding gripping device with the carton feeding and delivery mechanism ready to receive the next carton. Arranged beneath said turn-table 22 is a segmental step or track-cam 60, which is fixed to said table 3, and which extends around from a point of beginning or receiving end 61 abutting said lifting-block to a terminal point adjacent to the carton closing means, as will subsequently ap pear. \Vhen the gripping-device 29 is lifted to normal operative position by the rising of the lifting block 55, its tracker-roller 59 is lifted by the lifting-block to the level of the traction surface of said trackcam 60, so that as the turn-table 22 rotates, the tracker-roller 59 rides off of the lifting-block 55 and on to the track-cam 60, consequently so long as the tracker-roller is thus engaged by the track-cam the grip ping-device 29 is maintained in raised and operative position while the turn-table carries the carton engaged on the same around to operative disposition relative to a cartonfi1ling or charging means.

The reference character 62 indicates a platform which is supported by the standards 2 to extend horizontally above the table 3 in suitably spaced relation thereto. Pivotally connected to the under side of said platform 62, so as to depend therefrom in front of said carton magazine 32, is a swinging'arm 63 provided at its lower end with a combined guide and ironing member 64. Normally said arm 63 is swung to one side to withdraw from a location in front of the magazine 32 said guide and ironing member 64. Prior to the movement of the turn-table 22, however, and after the delivered carton is opened and gripped, said arm 63 is swung downwardly to carry the guide and ironing member 64 over the opened carton for the purpose of pressing the same firmly down upon the turntable surface between the gripping lug 30 and the abutment-block 31, said member 64 also serving to guide the carton beneath the bottom of the magazine 32 for passage under the same as the turntable 22 begins its rotative movements (see Figure 5). The means for producing a properly timed oscillation of said swinging arm 63, comprises a vertical lever 65 pivoted to said bed 1, the upper free end of which is connected through a link 66 with said arm 63 at a suitable point intermediate the fulcrum and the free end of the latter. Said vertical lever 65 is oscillated by a connecting rod 67 pivoted thereto, the free end of which is provided with lateral roller projections 68 and 69, one of which is operatively engaged by a pushingcam 70, and the other of i which is operatively engaged by a retracting cam 71, said" cams 'bemg fixed on and rotated by said lay shaft 17.

Connected with the lower end of the magazine 32 is a horizontal segmental guard plate 72, which extends over the marginal portions of the turn-table 22 to a point of delivery of the cartons to a carton closing means. Said guard plate 72 is suitably supported, in proper spaced relation to the turntable. by a bracket member 73, or any other suitable means. As the turn-table rotates, the gripped and open cartons are carried beneath said guard plate 72. and'are held by the latter against accidental displacement from the gripping means, as the same are carried by the rotation of the turn-table toward the carton filling or charging mechanism.

Mounted upon said platform 62 is a hopper 74 with which is associated a rotatable agitator 75, driven by the chain 76 from a sprocket wheel 77 mounted u )on said transverse lay shaft 13. The goods to be placed within the cartons are deposited in said hopper 74. As illustrative of the use and operation of the machine we have chosen to show the same as adapted to fill or charge the cartons with a plurality of small pieces 78, such, for example, as candy coated chewing gum tablets, candy pieces, cough drops and similar goods, although it will be understood that with suitable modification of the hopper and goods delivery mechanism many other kinds of goods or articles may be operated upon by the machine and inserted into the cartons handled by the same. Connected with the hopper 74 are a series of downwardly inclined chutes 79 corresponding in number to the number of articles desired to be placed within the carton. The rotary agitator 75 operates to assure the filling of the chutes 79. These chutes 79 are provided with suitably disposed delivery ends 80 leading down to a desired point above the turntable 22. The delivery ends 80 of the chutes are provided with suitable check and release devices 81, the timed operation of which through the link transmission 82 actuated by the cam 83 fixed on the transverse lay shaft 13, impels the properly timed release of one article from each chute for delivery to the carton filling devices. The delivery ends 80 of said chutes 79 terminate upon. a thin horizontal goods supporting plate 84 which extends over the surface of the turn-table 22.

By reason of the intermittent movement of the turn-table 22, the open carton, as gripped and held thereon by the gripping devices, are eventually brought to rest in properly alined relation to a carton filling or charging mechanism. The said carton filling or charging mechanism comprises a transversely disposed guide bracket 85', in the guides of which is mounted a reciprocatory gauge plunger 86. Said guide bracket 85 is fixed upon said table 3, and is so positioned adjacent and relative to the turn-table 22 that the gauge plunger 86 will be longitudinally alined with the open carton, when the latter is stopped in position ready to be filled, and so that forward or inward movement of said gauge plunger 86 will cause the same to enter through the outer end of the open carton whereby its free end may be passed throu h the latter to project beyond the inner on of the same.

relative to the opposite sideof'said turntable 22, and so as to be in transverse alinewardly to occupy a position paralleling and in front of the discharge ends 80 of said goods delivery chutes 79. The outer side 90 of said-"collocating frame 89 rests upon or is closely adjacent to the surface of said goods supportin plate 84, thus serving as a stop against W ich'th-e goods or pieces 78, as they are delivered from the chutes, are brought to rest and alined in front of the inner end of the carton, While the inner side. of the collocating frame is upwardly spaced from the goods supporting plate 84 so that the pieces 78 may pass beneath the same to enter said collocating frame. Said 'inner side 91 is provided with laterally projecting guard lips 92, which border the discharge ends of the chutes and serve to guide the pieces 78 as they pass under said inner side 91 of the collocating frame. Associated with said collocating frame 89 intermediate its sides, is a longitudinally disposed centrally positioned guard bar 93 which is spaced upwardly from the goods supporting plate 84 so that the pieces lie beneath the same when received within the collocatingframe. baid guard bar 93 serves to prevent the pieces 78 from yielding upwardly with consequent displacement from the train thereof when subjected to the pressure incident to their impulsion into, the carton. The

end of the collocating frame 89 is provided with a lip 94 beneath which the upper clos-' ing flap of the inner end of the carton is disposed, when the latter isstopped 1nv position to receive the pieces 78. The reference character 95 indicates a chargin plunger having at its rear end an upwardly ing portion 96 provided with an openlng 97 which straddles or receives said guard bar Fixed upon the opposite side of the tabled, adjacent and extend-- 93; connected by said portion 96 with said charging plunger 95, and upwardly offset relatlve thereto, is a rearwardly extending tail-piece 98, which is pivotally connected with said slide-bar 88. Prior to the operation of the carton filling mechanism, the release devices 81- release one piece 78 from each chute 80, so that the required number of pieces enter the collocating frame 89 in alined side by side relation in front of the charging plunger 95. The timed actuation of the gauge plunger 86 and char ing plunger 95 is such that the same mutuafiy cooperate to bunch and insert the pieces 78 into the carton disposed to receive the same. In operation, a forward movement is imparted to the gauge plunger 86 whereby the same is thrust endwise through the carton, with its forward end projecting slightly outward from th inner end of said carton, {the parts occup ing the positions indicated in Figure 6). he actuation of said gauge plunger is suchethat the same remains stationary in said inwardly thrust position while the initiative forward movement of the charging plunger 95 takes place. The initiative forward movement of the charging plunger 95 causes the same to engage the train of pieces 78 and to thrust the same together against the backing afforded by the stationary auge plunger 86, to thereby first the pieces 78 together in contact one with another (as illustrated by Figure 7 of the drawings). Upon completion of the initiative bunching movement of said charging plunger 95, the gauge plunger 86 is actuated to produce a retractive or withdrawing movement of the same which is synchronizedwith the continuedforward movement of said whereby the bunched pieces'78 are advanced toward the inner open end of the carton to pass therethrough and to thereupon enter charging plunger 95,

close upor unch close side by-side turned to normal initial position, and the charging plunger 95 is at the same time withdrawn or retracted to its normal'position ready for the next operation. The means for producing the above-described timed actuation of the gauge plunger 86, comprises an upwardly extending lever 99 which is pivotally connected with said bed 1, and'the upper free end of which is pivotally inter'connected with said gauge plunger 86 by a link 100. Journaled in bearings 101 supported by said bed 1 is a shaft 102, which isrotated from said driving shaft 5 through the intermeshed bevel gears 25, 26 and 103.

Fixed upon and rotated by said shaft 102 is a gauge plunger actuating cam Wheel 104 in its face. Connected with said lever 99, intermediate its free end and its fulcrum, is a connecting rod 106 having a bifurcated end 107 which straddles said shaft 102 so as to guide the reciprocatory' movements of said connecting-rod 106, said bifurcated end 107 having a roller projection 108 entered in said cam groove 105, whereby the desired timed motion is imparted to said connecting rod. The means for producing the above-described timed actuation of the charging plunger 95, comprises an upwardly extending lever 109 which is pivotally connected with said bed 1, and the upper free end of which is pivotally interconnected with said slide-bar 88, operating said charging plunger, by means of a link 110. Fixed upon and rotated by said shaft 102 is a charging plunger actuating cam wheel 111 having a properly shaped cam groove 112 in its face. Connected with said lever 109, intermediate its free end and its fulcrum, is a connecting rod 113 having a bifurcated end 114 which straddles said shaft 102 so as to guide the reciprocatory movements of said connecting rod 113, said bifurcated end 114; having a roller projection 115 entered in said cam groove 112, whereby the desired timed motion is imparted to said connecting rod 113. The plunger actuating means thus described is most clearly illustrated in Figures 1, 2 and 6 of the accompanying drawings.

Upon completion of the charging operations, as above described, whereby the desired contents are deposited within the carton, the latter is ready to be closed, and to this end means are provided to remove the filled carton from the turn-table, and then propel the same through the carton flap closing and tucking means, which is so located that its receiving end is conveniently adjacent to that point of the turn-table 22 where the cartons are stopped subject to the charging operations, and so that a simple direct movement quickly slides the filled carton to the closing mechanism withoutdanger of disturbing or dislodging the con tents placed therein. The first step incident to the transfer of the filled carton to the closing mechanism is to release the carton gripping means of the turn-table 22 from operative holding engagement with said filled carton. When the turn-table 22 stops itsrotative movement to dispose a carton in goods receiving position, the tracker roller 59 of the gripping device 29 rides off the terminal end of said track cam 60 on to a normally raised drop block 116, which is vertically movable through an opening 117 in said table 3, and

which is positioned adjacent to the terminal end of said track cam 60 witlrits upper end flush with the level of said track cam.

The said drop block 116 remains in normal raised position during the time the carton is being charged, so that the gripping lug of the gripping device 29 is retained in operative holding engagement with the carton during the charging operations. Upon completion of the carton charging operations, however, the said drop block 116 is subjected to a timed actuation which lowers or drops the same, thereby permitting the gripping device 29 to swing downward to withdraw said gripping lug 30 downwardly and clear up the turn-tablesurface, whereupon the filled carton may be engaged and bodily moved laterally to slide the same off the turn-table surface and into operative relation to the closing mechanism (see Figure 9). The means for roducing the desired timed operation of said drop block 116 comprises a lever 118 pivoted to the under side of said table 3, and to the inner end of which is attached said drop block, while the outer end of said lever is downwardly off-set and provided with a roller projection 119 which operatively engages the underside of an actuating cam 120 fixed on and rotated by said lay shaft 17. A pullspring 121 interconnected between the inner end of said lever 118 and the bed 1 serves to maintain the lever in operative engagement with said actuatin cam 120. In order to assure the downward swinging movement of the gripping device 29, when released by the dropping of said drop-block 116, so that any tendency of its gripping lug 30 to cling to holding relation to said carton is positively overcome, there position beneath the free end of said tripping lug 122. Pivoted to the under side of said table 3 is a trip lever 125, to one end of which is connected the lower end of said trippin 124, while the opposite end is engaged in an eye or opening 126 in the inner end of said drop block actuating lever 118. When said drop-block actuating lever is upwardly swung to hold said drop-block in normal position, the trip lever 125 is oscillated to hold the trip-pin 124: downwardly withdrawn, whereas, when the drop-block actuating lever is downwardly swung to drop said dropblock, the trip lever 125 is simultaneously oscillated to raise said trip-pin 124, which in turn pushes upwardly on said tripping lug 122 to positively actuate a downward swinging movement of said gripping device 29, as will be clearly evident from an inspection of Figure 9 of the drawings. The filled carton being released from engagement with the gripping device is now ready to be transferred to the closing mechanism.

Each carton C is provided at opposite ends of its side C with side flaps (J and at oppo- -site ends of its side 0* with similar side flaps C while the bottom or under face C is provi ed at one end with an end flap G having at its extremity a tuck tongue C and the top or upper face 0 is provided at the opposite end with an end flap 0 having at its extremity a tuck tong'ue C.

The carton closing mechanism is disposed carton closing mechanism. Said carton closing mechanism consists of a pair of longitudinally parallel supporting bars 127, each carrying an inwardly projecting longitudinal slidew'ay bar 128 for supporting the cartons as they are moved sideways between the flap closing means. Suitably disposed inner bearings 129 and outer bearings 130 are provided adjacentto the respective ends of and beneath the slideway provided by the bars 128. Journaled in the inner bearings 129 is a transverse shaft 131 upon which is fixed a driving sprocket 132. Said shaft 131 extends toward said lay shaft 9, and is driven thereby through the bevel gears 133 and 134.

J ournaled in said outer bearings 130 is the supporting shaft 135 of an idler sprocket 136. Running over said sprockets 132 and 136 is a conveyor chain 137 having, at properly spaced intervals, impelling pieces 138 which ride between said slideway bars 128 so as to engage and propel the cartons through the closing mechanism. Supported in connection with said slideway bars 128, at

the receiving end ofthe closing mechanism are flap closing and tucking devices which will be subsequently more fully described. Associated with the carton closing mechanism, is a means for transferring the filled carton from the turn-table 22 into the receiving end of said closing mechanism for movement through the latter. The transferring meanscomprises a transfer rake 139 provided with a lever arm or tail-piece 140 extending forwardly from the outer side,

thereof. The forward free end of said arm or tail-piece 140 is pivotally connected with the upper end of an oscillatable lever member 141 which is pivotally connected with said bed 1 to project upwardly therefrom. The means for oscillating said lever member 141 to produce a timed operation of said transfer rake 139 comprisesan eccentric 142 mounted upon and operated by said transverse lay shaft 13, and interconnected with said lever .member 141 by a connecting rod 143. Mounted upon a supporting bracket 144, at one side of said carton closing mechanism,'is a fixed guide-block 145 provided with a guide cam-groove 146. Cooperatmg with said cam-groove is a pivoted lift-cam 147. Rigidly connected with the tail-piece 140 of said transfer rake 139 is a guide-arm 148 which extends rearwardly toward said guide-block 145, and which is providedat its free end with aroller projection 149 which enters and rides in said guide cam-groove, 146 of said guide-block 145. transfer rake 139 into operative position relative tothe filled carton, for the purpose of moving the latter off the turn-table 22 and into the carton closing mechanism, it is necessary to lift or swing the transfer rake up-. ward to pass the same rearwardly over the carton and down behind the same.

This motion is accomplished as follows When the rearward oscillation of the lever member 141 moves rearwardly the transfer rake 139, the roller projection 149 of the guide-arm 148 is carried into engagement with the lift-cam 147, which causes the same to ride upwardly thereon through the upper portion of the guide cam-groove 146 as the parts move rearward, with the result that the guide-arm 148 is swung upward im parting a like upward movement to said transfer-rake 139 so thatthe same is raised above'the carton as it passes over the latter. As the limit .of rearward movement is reached, the roller projection drops downward at the rear end of said guide camgroove to the lower level of the latter, so that the transfer rake drops behind the filled carton in position to engage the same. Upon forward movement'of the transfer rake, the roller projection 149' of the guide-arm 148 passes forwardly through the lower level of the guide-cam groove, and in passing beneath the lift-cam 147 swings the same upwardly on its pivot whereby it. is caused to yield to such forwardmovement, dropping back to operative position upon the passing of the roller projection thereby, and. thus being ready to exercise its'lifting function at each repetition of the reciprocatory' movement of the transfer-rake. The transferrake 139 being positioned to engage the filled carton, the forward movement of the transfer rake slides the carton forwardly oil the turn-table 22, causing the same to enter the carton closing mechanism. The said transfer-rake is provided on each side wit-h for- To move the in Figure 11.

to extend forwardly from the inner or receiving end of said carton closing mechanism, on each side thereof, are tuck tongue turnin guides, the same comprising a pair of guide bars 151 and 152, each having a convolved inner face. The respective guide bars 151 and 152 are associated together with their convolved faces opposed and spaced apart to provide a tortuous or twisted guideway 153 of proper shape to receive and act upon the tuck tongues of the carton end flaps so as to bend the same over and inwardly as they pass through said guideways. The-arrangement and positioning of said pairs of guide bars 151 and 152 is such that one pair or set of said guide bars is disposed to act u on the end flap C and its tuck tongue U which spring from the under or bottom face C of the carton, while the other pair or set of said guide bars is disposed to act upon the-end flap C and its tuck tongue (1 which spring ifrom the upper or top face C of the carton. The forward ends of the guide bars 151 are cut away at their sides, as at 15 1, to provide side flap turning portions. As the transfer rake 139 moves the carton into position between the guide bars 151, the side flaps C are engaged and turned inwardly from the plane of the side C to extend at right angles to the latter and partially across the open ends of the carton, as shown As the filled carton enters into engagement with the closing mechanism, the end flaps G and C respectively enter the'guideways 153, and thereupon an impelling piece 138 of the conveyor mechanisms rides into engagement with the entered carton and propels the same forward, whereby the tuck-tongues C and C are acted upon in the manner indicated in Figures 11 to 15 inclusive. Located at the outer ends of said pairs of guide bars 151 and 152 are rotary tucking devices, the same comprising tucker rolls 155 which are mounted on verticalspindles 156 so as to rotate in a horizontal plane. Said spindles 156 are journaled in said supporting bars 127 and slideway bars 128 to extend downwardly through an extension 157 of the table 3, and fixed upon the lower ends of said spindles are spur gears 158. Slidably supported between guides 159 fixed to the under side of said extension 157 so as to reciprocate therein, is a rack-plate 160 provided on its opposite sides with rack-members 161 which respectively mesh with said spur gears 158. A timed reciprocation of said rack-plate 160 operates to produce. a properly synchronized operation of the tucker-rolls 155 upon the carton as the latter is propelled past the same. The timed reciprocation of said rack-plate 160 is produced by a levermember 162, which is pivotally connected with said bed 1 to extend upwardly therefrom, and the free end of which is interconmember 162. The said tucker-rolls 155 are provided in their peripheries at their inner sides with a'receiving groove 166 the sides of which form a dihedral angle. Said receiving grooves communicate at their rearward ends with downwardly inclined tucking grooves 167 diminishing gradually in depth until merged with the outer periphery or circumference of the tucker-rolls. As the cartons are propelled out of the guideways 153, the end flaps C and C with their inwardly turned tuck-tongues .are turned slightly downward, and thesame ride into said receiving grooves 166 of the tucker rolls, to occupy positions therein (as shown in Figure 16) ready for the tucking operations. Rotary motion is now imparted to the tucker rolls, so that the tucking grooves 167 are caused to ride against the end flaps and their inwardly turned tuck-tongues, whereby the diminishing depth and changing positions and shape of the said tucking grooves forces the end flaps into closed position and at the same time causes the tuck tonguesto enter the ends of'the carton within the faces of the same. The rotation of the tucker rolls finally carries their smooth vertical faces 168 into which the tucliing grooves 167 merge, against the end flaps to complete the closing movement thereof. In order to provide for a final and complete endwise thrust against the closed carton so as to assure a complete closure of the ends, and to overcome any tendency of the end flaps to spring open, one or both of the tucker rolls 155 may be provided on their smooth vertical faces 168 with a pinching or compression tit- 169, which rides into engagement with the adjacent end-flap to produce an additional inward thrust or compression of the same into its normal closed position with its tuck-tongue firmly thrust into tucked engagement within the carton end. The above operations will be understood from an inspection of Figures 16, 17 and 18. Upon thecompletion of the "endflap closing and tucking operations the filled carton is impelled away from the tuckerrolls and rides between the guard bars 170 to be finally ejected from the machine on to a table or other suitably arranged receiver (not shown). In order to prevent upward and outwarddisplacement of the cartons, as they are passed through the carton closing mechanism, there are provided the upper or top slideway bars 171, the inner margins of which overhang the passageway through which the cartons move, so as to engage synchronized for proper correlation as will be clearly evident.
